Install in the reverse order of removal.

|
Do not use the same A/C recovery / charging station as conventional belt-driven compressors. |
|
•
|
Since the electric compressor uses high-voltage, POE oil with high resistivity should be used. |
|
•
|
If PAG oil mixes into the POE oil of the system, dielectric
breakdown may occur due to decreased volumetric resistivity and the A/C
compressor may not work. |
|
|
•
|
If you''re installing a new evaporator core, add refrigerant oil (PAG OIL). |
|
•
|
Replace the O-rings with new ones at each fitting, and apply a
thin coat of refrigerant oil before installing them. Be sure to use the
right O-rings for R-134a to avoid leakage. |
|
•
|
Immediately after using the oil, replace the cap on the container, and seal it to avoid moisture absorption. |
|
•
|
Do not spill the refrigerant oil on the vehicle; it may
damage the paint; if the refrigerant oil contacts the paint, wash it off
immediately. |
|
•
|
Apply sealant to the grommets. |
|
•
|
Make sure that there is no air leakage. |
|
•
|
Charge the system and test its performance. |
|
•
|
Do not interchange the inlet and outlet heater hoses and install the hose clamps securely. |
|
•
|
Refill the cooling system with engine coolant. |
